1. MEL - getting values from array returns without using variables

   

   Topic by PolyHertz · Jan 2011 · Home› Technical Talk

   Is there a way to get a certain value from an array retun without first assigning the return to a variable? For instance, I'd like to use something like: `ls -sl -fl`[0]; instead of: $val = `ls -sl -fl`; $val[0]; Just seems like a waste to be creating variables for one time uses.

   I think JsTools or such, made an extra procedure to return the first element for example, to save code and such. I wonder if the variables get cleared from memory at the end of procedure codes, or at the end of entire script call ... But well, I usually just used $tmp or such, It's really insignificant.
